NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 417,772, dated December 24, 1889.

Application tiled August 23, 1889. Serial No. 321,763. (No model.)

T0 @ZZ whoml t may concern:

Be it known that we, JAMES XV. DEERING and ROBERT D. FOSTER, citizens of the United States, residing at Harwood, in the county of .ter appear, and be particularly pointed outin the claim.

Referring tothe drawings, Figure l is a side eleva-tion of a railway-j oint pro vided with n utlocks constructed in accordance with our invention. Fig. 2 is a detail in perspective of the bolt-nut and lock detached from the rails. Fig. 3 is a detail of the bolt; Fig. 4, of the nut; Fig. 5, of the lockingpin- Like numerals of reference indicate like parts in all the figures of the drawings.

1 represents two adjacent rail-sections having the usual iish-plates 2, and 3 represents the bolt for binding the saine together. The bolt 3 is provided with a longitudinal slot 4, extending from near its inner end to about midway its length, and over the holt is threaded the nut 5, the outer 'face ot which is provided with right-angularly disposed transverse grooves and diagonally-disposed similar grooves 6, either ot which is adapted to register with the longitudinal slot l of the bolt.

7 represents the locking-key, and the same consists of a heavy rigid base portionS and a reduced remaining spring portion 9, bent over upon the base portion, as at 10, havinga central depression 11 and terminating in a dcpending tongue or end 12, adapted to come into contact with a cut-away shoulder 13, formed on the end ot the rigid portion ot' the key or pin. The nut being mounted in position upon the bolt', it will be apparent that one or the other of the recesses will be in line with the longitudinal opening thereof, and the tern1inal 12 of the pin is depressed untilin contact with the cut-away portion of the base of the pin, and thus form a tapered entering end, and is inserted into one of the grooves and through the elongated opening in the bo'lt and beyond the outer edge of the opening and until the central depressed portion l1 is in the end ot the longitudinal slot, when it will be apparent that the pin is prevented from any accidental displacement by reason ot the spring portion thereof and the location of the oppo site bend at each side of the depression 11.

Having described our invention, what we claim is- The combination, with thebolt 3, having the slot 4, of the nut 5, threaded thereon and hav ing the transverse pair and diagonal pair of recesses 6 in its outer face, one of which registers'with the slot 4f, and the pin or locking-key 7, having the thickened rigid base portion 8, terminating at one end in the reduced portion, bent, as at lO, to form the` spring-tongue 9 and having a central depression l1 lower than an'd between the ends of the spring and taking against the end of the slot, and the depending tongue 12, adapted `to be depressed upon the end ot the base S, which is cut away, as at 13, to forni a reduced entering end, substantially as specied.

In testimonythat we claim the foregoing as our own we have hereto atixed our signatures in presence of two witnesses.

JAMES W. DEERING. ROBERT D. FOSTER.
